Untying chronic pain: prevalence and societal burden of chronic pain stages in the general population - a cross-sectional survey.

ABSTRACT:

Background

Chronic pain is a major public health problem. The impact of stages of chronic pain adjusted for disease load on societal burden has not been assessed in population surveys.

Methods

A cross-sectional survey with 4360 people aged ?? 14 years representative of the German population was conducted. Measures obtained included demographic variables, presence of chronic pain (based on the definition of the International Association for the Study of Pain), chronic pain stages (by chronic pain grade questionnaire), disease load (by self-reported comorbidity questionnaire) and societal burden (by self-reported number of doctor visits, nights spent in hospital and days of sick leave/disability in the previous 12 months, and by current unemployment). Associations between chronic pain stages with societal burden, adjusted for demographic variables and disease load, were tested by Poisson and logistic regression analyses.

Results

2508 responses were received. 19.4% (95% CI 16.8% to 22.0%) of participants met the criteria of chronic non-disabling non-malignant pain. 7.4% (95% CI 5.0% to 9.9%) met criteria for chronic disabling non-malignant pain. Compared with no chronic pain, the rate ratio (RR) of days with sick leave/disability was 1.6 for non-disabling pain and 6.4 for disabling pain. After adjusting for age and disease load, the RRs increased to 1.8 and 6.8. The RR of doctor visits was 2.5 for non-disabling pain and 4.5 for disabling pain if compared with no chronic pain. After adjusting for age and disease load, the RR fell to 1.7 and 2.6. The RR of days in hospital was 2.7 for non-disabling pain and 11.7 for disabling pain if compared with no chronic pain. After adjusting for age and disease load, the RR fell to 1.5 and 4.0. Unemployment was predicted by lower educational level (Odds Ratio OR 3.27 [95% CI 1.70-6.29]), disabling pain (OR 3.30 [95% CI 1.76-6.21]) and disease load (OR 1.70 [95% CI 1.41-2.05]).

Conclusion

Chronic pain stages, but also disease load and societal inequalities contributed to societal burden. Pain measurements in epidemiology research of chronic pain should include chronic pain grades and disease load.

Project description:BACKGROUND:Chronic pain conditions and mental disorders have high prevalence rates in military populations. However, few investigations have examined the comorbidity between chronic pain conditions and specific mental disorders among Canadian active military personnel. METHODS:We conducted a secondary analysis of data from the 2013 Canadian Forces Mental Health Survey (CFMHS) concerning the population of regular members. Diagnostic interviews assessed the presence of mental disorders, and participants self-reported chronic pain conditions (i.e., arthritis, back problems, musculoskeletal conditions, migraines) and indicators of pain severity. We used multiple logistic regressions to assess associations between chronic pain conditions and mental disorders. We used cross-tabulations to assess the prevalence of pain severity indicators in comorbid relationships compared with the chronic pain condition alone. We used moderation analyses to examine the interactions between pain condition by pain severity, and pain condition by activity limitation, respectively, on mental disorders. RESULTS:The CFMHS included data from 6696 regular members and had a response rate of 79.8%. About one-quarter (n = 1761) of military personnel reported having chronic pain. In the fully adjusted model, all assessed pain conditions were significantly associated with posttraumatic stress disorder (PTSD) (odds ratio [OR] range 1.86-2.55), and several pain conditions were associated with major depressive episode, generalized anxiety disorder and panic disorder. Back problems were significantly associated with all mental disorders apart from alcohol use disorders (OR range 1.40-2.17). Cross-tabulations showed higher prevalence estimates of endorsement for pain severity indicators among pain conditions and comorbid mental disorders, compared with pain conditions alone. Formal moderation analyses showed a significant relationship between migraine and activity limitation on PTSD. INTERPRETATION:Chronic pain conditions are prevalent and co-occur with mental disorders among Canadian regular force members. Greater understanding of these chronic pain conditions and mental disorders and their impact on people's abilities to adapt to both military and civilian life is needed.

Project description:BackgroundCharacteristics of patients receiving long-term opioid therapy (≥ 6 months) for chronic noncancer pain are poorly understood. We conducted a cross-sectional survey of this patient population to explore demographic variables, pain relief, functional improvement, adverse effects and impressions of an educational pamphlet on long-term opioid therapy.MethodsWe invited 260 adult patients presenting to the Pain Management Centre at the Hamilton General Hospital, Hamilton, Ontario, with chronic noncancer pain to complete a 20-item survey. Patients who presented for procedures were not eligible for our study. We used adjusted logistic regression models to explore the association between higher morphine equivalent dose and pain relief, functional improvement, adverse events and employment.ResultsThe survey was completed by 170 patients (a response rate of 65.4%). Most respondents (87.6%; 149 out of 170) were receiving long-term opioid therapy, and the median morphine equivalent dose was 180 mg daily (interquartile range 60-501). Most respondents reported at least modest (> 40%) opioid-specific pain relief (74.1%; 106 out of 143) and functional improvement (67.6%; 96 out of 142), and 46.5% (66 out of 142) reported troublesome adverse effects that they attributed to their opioid use. Most patients were receiving disability benefits (68.3%; 99 out of 145) and, among those respondents who were less than 65 years of age (90.3%; 131 out of 145), 10 (7.6%) were working full-time and 14 (10.7%) part-time. In our adjusted analyses, higher morphine equivalent dose was associated with greater self-reported functional improvement (odds ratio [OR] 1.45, 95% confidence interval [CI] 1.07-1.96) but not with pain relief (OR 1.38, 95% CI 1.00-1.89), troublesome adverse effects (OR 0.92, 95% CI 0.70-1.20) or employment (OR 0.80, 95% CI 0.56-1.15).InterpretationMost outpatients receiving long-term opioid therapy for chronic noncancer pain at a tertiary care chronic pain clinic reported at least moderate pain relief and functional improvement; however, adverse effects were common and few patients were engaged in competitive employment.
